I am going to be purchasing a vortech kit with the aftercooler for my 2003 GT. The kit is used and comes with everything except MAF, injectors, and a fuel pump. I also know that I will need a dyno tune afterwards. I am thinking of running 8-10 psi...Bottom line I just want to stay on the safe side. My question is do I need to get a bigger MAF and fuel pump? DOes it all depend on the size injectors I get? I am thinking between 38-42lbs injectors...I know I need a bigger fuel pump, but does this go hand in hand with a bigger MAF. Anyone who can chime in and share some knowledge about this would be great...Thanks.

If I'm not mistaken, doesn't the kit come with all that stuff? I've seen them with the 255lph fuel pumps, injectors, everything for the install.

Depends on where you buy it.

I'd pick up bigger injectors for sure, same with a fuel pump that will flow more. You can get by without a larger MAF, but I think the rest of the tubing will be larger than your MAF at that point, and you'll have a bottleneck and may peg the MAF. The MAF is just a good idea, not really -necessary-

Might want to look into a boost a pump instead of a bigger fuel pump. Not sure if that would work for your situation, but if it would it would save you a lot of hassle.
